The best way to prevent losses is the use of poisoned bait supplemented by tillage and seeding methods which restrict egg laying and imprison the young grasshoppers in the ground after they hatch. Bait is most effective while grasshoppers are still on their hatching grounds or massed along field margins. It should be put out when grasshoppers are doing their first feeding of the day. This usually occurs between 6 and 10 a.m. at temperatures of 70° to 80°F. Bait should not be spread unless grasshoppers are actively feeding. In mixing and distributing the poisoned bait care should be taken to prevent injury to persons and farm animals. Seeding grain only on plowed or summer-fallowed ground and plowing infested stubble before the eggs hatch greatly reduces the quantity of bait needed for control and decreases the liability of crop injury. Cooperation in the use of control methods by all the farmers in a community is necessary for best results." -- p. i</p>Crops Against the Wind on the Southern Great Plains2012-08-14T16:17:07-05:00http://digital.library.unt.edu/ark:/67531/metadc97283/<p><a href="http://digital.library.unt.edu/ark:/67531/metadc97283/"><img alt="Crops Against the Wind on the Southern Great Plains" title="Crops Against the Wind on the Southern Great Plains" src="http://digital.library.unt.edu/ark:/67531/metadc97283/small/"/></a></p><p>"This bulletin briefly traces the circumstances which have created the soil problems in the southern Great Plains and shows how the hand of man has hastened present troubles. But it goes further and deals with the methods now being used to solve the problem on nature's own terms." -- p. 2-3. Some of the solutions discussed include contour farming, terraces, water conservation techniques, crop lines, and revegetation.</p>Culture and Pests of Field Peas2012-08-14T16:17:07-05:00http://digital.library.unt.edu/ark:/67531/metadc97271/<p><a href="http://digital.library.unt.edu/ark:/67531/metadc97271/"><img alt="Culture and Pests of Field Peas" title="Culture and Pests of Field Peas" src="http://digital.library.unt.edu/ark:/67531/metadc97271/small/"/></a></p><p>This bulletin discusses the culture of the field and diseases and insects which commonly afflict it.

The disease spread rapidly to nearly all parts of the range of the native chestnut, and the remaining stands of the southern Appalachians face certain destruction. The present known distribution, its symptoms, and the fungus that causes the disease are described. The blight fungus itself does not have any effect upon the strength of chestnut timber, and blight-killed trees can be utilized for poles, posts, cordwood, lumber, and extract wood. Search is being made for native and foreign chestnuts resistant to the disease in the hope of finding a tree suitable for replacing the rapidly disappearing stands. Seedlings of Asiatic chestnuts, which have considerable natural resistance even though not immune, are being tested in the United States." -- p. ii</p>The Farmer Looks Ahead2012-08-14T16:17:07-05:00http://digital.library.unt.edu/ark:/67531/metadc97263/<p><a href="http://digital.library.unt.edu/ark:/67531/metadc97263/"><img alt="The Farmer Looks Ahead" title="The Farmer Looks Ahead" src="http://digital.library.unt.edu/ark:/67531/metadc97263/small/"/></a></p><p>This bulletin provides criteria by which farmers may determine how much they should plan to produce in a given year. There "are four major yardsticks: 1) How much should farmers produce, thinking only of the requirements of domestic consumers, plus; 2) What they can expect to ship to foreign countries in the next few years? 3) How much should they produce, thinking only of the requirements of soil conservation? 4) How much should farmers produce, thinking only of their incomes?" -- p. 3</p>Farm Practice with Lespedeza2012-08-14T16:17:07-05:00http://digital.library.unt.edu/ark:/67531/metadc97260/<p><a href="http://digital.library.unt.edu/ark:/67531/metadc97260/"><img alt="Farm Practice with Lespedeza" title="Farm Practice with Lespedeza" src="http://digital.library.unt.edu/ark:/67531/metadc97260/small/"/></a></p><p>"The use of lespedeza as a farm crop has rapidly increased during the past few years. The increase in the use of lespedeza is due partly to the excellent results that have been obtained by the farmers who have been growing the Common variety, for hay and for pasture and soil improvement, but more particularly to the introduction of some new varieties that produce better yields, are adapted to a wider range of climatic conditions, and are generally better suited to the needs of the average farm than is the Common variety. This bulletin is based on information collected from farmers located in the States of Virginia, North Carolina, Tennessee, and Kentucky who are growing lespedeza regularly as a farm crop. The information includes methods of seeding, varieties used, the place in the cropping system usually occupied by lespedeza, and practices that have developed in connection with the production and use of the crop in these States." -- p. 1</p>Infectious Anemia (Swamp Fever)2012-08-14T16:17:07-05:00http://digital.library.unt.edu/ark:/67531/metadc97278/<p><a href="http://digital.library.unt.edu/ark:/67531/metadc97278/"><img alt="Infectious Anemia (Swamp Fever)" title="Infectious Anemia (Swamp Fever)" src="http://digital.library.unt.edu/ark:/67531/metadc97278/small/"/></a></p><p>Infectious anemia (which is also known as swamp fever) is a disease which afflicts horses and mules and results in significant financial losses for farms every year. This bulletin discusses the causes and forms of the disease, the accompanying anatomical changes in infected animals, the diagnostic process, and control measures which can be taken to prevent further spread of this serious illness.</p>
